The actual reason for all of this is because both major American political parties have discovered, as many corporations have over the past few years, that the only thing that matters when it comes to persuasion is appeals to one's identity and emotions directly. As it turns out, people don't give a crap about logic, reason, facts, deduction... our day-to-day lives are complex enough as it is, only a few of us can actually afford the time to research all of the media's claims, and thus, reactionary, controversial, attention-grabbing headlines (not full articles, who reads those anyways?) dictate what people believe is the truth. So yeah, you and I look at that modal popup and think, "ew gross, why are you trying THIS hard to shove this negative image of your opponent down my throat, before I can even see a single fact about you and your campaign?", but I can totally see why they would do such a thing. People are very susceptible to being persuaded by these strong emotional accusations—it seems to me that the dialog is saying, "hey, you're not one of those filthy TRUMP supporters, ARE YOU? If not, prove it by clicking this button below." I believe that such a persuasive device is far more effective than either of us can imagine.
